Implementations

impl UnitExponents

pub fn powi(self, n: i32) -> Self

Raises self to an integer power.

Examples

use dyn_quantity::UnitExponents;

let exponents = UnitExponents::from([0, 1, 0, 2, 0, -2, 0]);
let array: [i32; 7] = exponents.powi(2).into();
assert_eq!(array, [0, 2, 0, 4, 0, -4, 0]);

pub fn try_nthroot(self, n: i32) -> Result<Self, RootError>

Tries to calculate the nth root of self. This operation fails if any of the exponents is not divisible by n.

Examples

use dyn_quantity::UnitExponents;

let exponents = UnitExponents::from([0, 2, 0, 2, 0, -4, 0]);

// It is possible to calculate the square root:
let array: [i32; 7] = exponents.clone().try_nthroot(2).unwrap().into();
assert_eq!(array, [0, 1, 0, 1, 0, -2, 0]);

// But not the cubic root (not all exponents are divisible by 3):
assert!(exponents.try_nthroot(3).is_err());

Trait Implementations

impl Clone for UnitExponents

fn clone(&self) -> UnitExponents

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnitExponents

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for UnitExponents

fn default() -> UnitExponents

Returns the “default value” for a type.

impl Display for UnitExponents

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Div for UnitExponents

type Output = UnitExponents

The resulting type after applying the / operator.

fn div(self, rhs: Self) -> Self::Output

Performs the / operation.

impl DivAssign for UnitExponents

fn div_assign(&mut self, rhs: Self)

Performs the /= operation.

impl From<[i32; 7]> for UnitExponents

fn from(array: [i32; 7]) -> Self

Converts an array of seven i32 values into UnitExponents.

The individual array elements are interpreted as follows:

• array[0]: Exponent of second
• array[1]: Exponent of meter
• array[2]: Exponent of kilogram
• array[3]: Exponent of ampere
• array[4]: Exponent of kelvin
• array[5]: Exponent of mol
• array[6]: Exponent of candela

impl From<UnitExponents> for [i32; 7]

fn from(value: UnitExponents) -> Self

Converts an UnitExponents into an array of seven i32.

The exponents are put into the array in the following order:

• array[0]: Exponent of second
• array[1]: Exponent of meter
• array[2]: Exponent of kilogram
• array[3]: Exponent of ampere
• array[4]: Exponent of kelvin
• array[5]: Exponent of mol
• array[6]: Exponent of candela

impl Mul for UnitExponents

type Output = UnitExponents

The resulting type after applying the * operator.

fn mul(self, rhs: Self) -> Self::Output

Performs the * operation.

impl MulAssign for UnitExponents

fn mul_assign(&mut self, rhs: Self)

Performs the *= operation.

impl PartialEq for UnitExponents

fn eq(&self, other: &UnitExponents) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
